b7761af34d Conf: Replace keyword and symbol hash table with generic hash table.
The old hash table had fixed size, which makes it slow for config files
with large number of symbols and symbol lookups. The new one is growing
according to needs.

9b9a7143c4 Conf: Fixes bug in symbol lookup during reconfiguration
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.

The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.

bc7f4e0e34 Bump max symbol length to 64.
And move the constant to conf.h header.

Thanks to Alexander Chernikov for the patch.

Based on the patch from Alexander V. Chernikov.

26d92bb892 A hack to distinguish if..else from else: in case.
The old BIRD grammar needs two lookaheads to distinguish if..else from
else: in case, which caused the parser to fail on some combinations of
both expressions.

This patch replaces two tokens 'else' ':' by one token 'else:' to fix
that.

04dc62a011 Nested scopes could never have worked. My fault I wrote such a buggy code,
Pavel's fault that he's never tested shadowing of declarations in the filters.

cf_define_symbol() has been modified to check the scope of the symbol it's
given and it if it's an already defined symbol, but in a different scope,
a copy is created in the current scope and redefined to the new meaning,
the consequence being that it cf_define_symbol() now returns the new symbol
you need to use when assigning aux and aux2.

d272fe22dd Separated `official protocol names' used in status dumps from name templates
used for automatic generation of instance names.

	protocol->name is the official name
	protocol->template is the name template (usually "name%d"),
		should be all lowercase.

Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.
